If we are concerned about intelligent adversaries, then we need to use 
something cryptographically strong like SHA1. If not, then we only need 
to care about:
- speed
- probability of getting too many collisions in a "regular" usage 
scenario that does not involve an attacker.

I believe that my change increases the speed, has little chances of 
introducing too many _accidental_ collisions, so it's a reasonable 
change to make.
